Connecticut Earned Income Tax Credit

Connecticut’s earned income tax credit is a refundable state tax credit for eligible workers. It is claimed with the state income-tax return.

Who can apply

You must qualify for federal EITC and satisfy Connecticut rules, including full-year residency. Earned income, filing status, tax identification and any qualifying-child rules affect eligibility.

What help is available

The credit can reduce state income tax or contribute to a refund. Use the calculation and limits for the filing year.

Documents to prepare

  • Federal return, wage statements and self-employment income and expense records.
  • Social Security numbers required for eligible filers and children.
  • Full-year residency and qualifying-child records, where applicable.

How to get started

  1. Confirm federal and state eligibility

    Review the DRS EITC page and the correct year’s instructions.

  2. Complete Schedule CT-EITC

    Use information from the federal return and retain any calculation worksheets.

  3. File the Connecticut return

    Include the required schedule. If needed, look for qualified free tax-preparation help before the filing deadline.

After applying

DRS may request supporting records. Respond to the actual notice and retain the federal and state returns together.

Does self-employment count?

It can be earned income; retain income and expense records for the calculation.

Is this a monthly benefit?

No. It is claimed on an income-tax return.
